Odoo Customization
Changes to how Odoo behaves for your process: fields, views, reports, automations. Delivered as a separate module rather than edits in the database.
What the hour covers
Adding fields and views, changing what appears in lists and forms, setting up automated actions, preparing a printable document.
What is needed from you
An example of the document or screen in the shape you want it, and an explanation of why the standard version does not fit.
Why a module and not Studio
Studio edits live in the database and complicate upgrades and moving to another server. A separate module can be read, tested and rolled back.
